| Abstract: | Reactions of Pt2(μ-Cl)2(C∩P)2] (C∩P = CH2C(Me2)PBut2-C,P) with various anionic ligands differing in ligand bite and denticity have been investigated and the resulting products have been characterized by elemental analyses and NMR (1H, 13C, 31P, 195Pt) spectroscopy. Stereochemistry of the complexes has been deduced by NMR spectroscopy. Structures of Pt2(μ-SPh)2(C∩P)2], Pt2(μ-pz)2(C∩P)2], PtCl(Spy)(PBut3)], Pt2(μ-SCOPh)2(C∩P)2] and Pt{S2P(OPri)2}(C∩P)] have been established by single crystal X-ray diffraction analyses. The complex Pt2(μ-SPh)2(C∩P)2] adopts a sym cis configuration while other binuclear complexes exist in a sym trans configuration. The molecular structure of Pt{S2P(OPri)2}(C∩P)] revealed that complex comprises of two four-membered chelate rings but in solution a dimeric structure based on 195Pt NMR data has been suggested. |
